EEF-SX Specialty Polymer Aluminum Capacitors

Panasonic EEF-SX Specialty Polymer Aluminum Capacitors (SP-Caps) have super low ESR from 4.5mΩ to 9mΩ. The EEF-SX Series SP-Caps from Panasonic offer lower ESR and higher capacitance at the same case size than conventional products. Other features of EEF-SX Series SP-Caps include capacitance range from 82µF to 560µF, voltage range from 2V_DC to 6.3V_DC, and operating temperature range from -40°C to +105°C.
